Centrifugal pump |
摘要 |
The centrifugal pump has a pair of multi-stage sub-blocks wherein the impellers are shrink fitted onto the shaft. The impellers on the drive-side sub-block have shrunk fit regions in the side away from the inflow while the shrunk fit regions of the impellers remote from the drive are located on the inflow side. The shaft is made with a reduced shaft section to receive the impellers of the remote sub-block and permit the hubs of the impellers of this sub-block to be radially enlarged for shrink-fitting purposes. A center piece which separates the sub-pumps is connected via screw bolts and nuts with the last guide wheel of the drive-side sub-block.
